linopt::Transparent::phaseI_tableau

Use only in the MuPAD Notebook Interface.

This functionality does not run in MATLAB.

Syntax

linopt::Transparent::phaseI_tableau(tableau)

Description

linopt::Transparent::phaseI_tableau explicitly
starts an (ordinary) phase one of the simplex algorithm , i.e. rows
associated with infeasible basic variables are multiplied with -1
and another identity matrix with new slack variables is added to the
given tableau. As soon as an optimal tableau with relative costs 0
is found the calculation can be continued with linopt::Transparent::clean_basis and
the second phase of the simplex algorithm (linopt::Transparent::phaseII_tableau).

Examples

Example 1

The first simplex tableau is created and the first phase of
the simplex algorithm is started:
